this has to be fake cause if you go to their website and go to e92 m3 all the pics are copied from original bmw pics...the video posted is not even their own its a fifth gear one..and the dyno pics are of invalid links

It is a small company. But they are around for ages now. But i dont have first hand experience on what they do. In the past i saw alot of 325i mosselman turbo's.
I think some1 need to go inspect it over there. Too bad they are closed in my vacation.

Interesting, with my ECU flashed back to stock settings, i was getting 350 WHP at 100 degrees. So my baseline WHP is about 330. now that ess, and RPI has retuned my car, the power gains are tremendous. im expecting to get 370 WHP with the new exhaust.. but still i want that 400 WHP NA. I want this system!! NAOS!!
or maybe retrofit the GTS =D

Some of the power gain is achieved from raising the redline. I wonder how high it is? Max power is at 8600 rpm, so, maybe 8700.

The first order rough calculation (assuming torque is constant) is that the power gained is just the original power times the new redline/old redline. In this case that is only abotu 3-4%. Not much of the total gain but it all helps.

danm that is impressive... Love that its NA... That air box and cams do make a difference on tq with software, intake and exhaust. Had a similar set-up on my NA E46 M3 minus the Air-box)... Would love to see some more info on this, Im real interested to see some dyno charts and so on...
